f0 not compact soil beneath trees. No vehicle ,hall be allowed to par:;
under trees. No heavy materials shall be stored beneath Lrees. Resuits,•L
compaction cause water and air not to reach the roots and the tree

?. No cutting of large structural roots located near the base of the
trunk. 'lhese are essential in supporting the tree an(i holding it
upright: in high winds. Removal of these roots along one side is
often (lone because of a walk, paving, or building which is tieing
